The rest of the weekend shootings were scattered across Chicago. They happened as far north as West Rogers Park and northwest as Jefferson Park and as far south as the West Pullman neighborhood. The violence centered on the West Side, though. Seven of the shooting incidents on the West Side had more than one victim.

While the number of shootings was up from last year, the number of deaths was down. Last year, 12 people were killed and 44 wounded over the holiday weekend. This weekend, 13 more people were shot, but six fewer people were killed.

There were no shooting deaths for more than 48 hours starting late Saturday afternoon through late Monday.

The breakdown from the weekend is: Three people killed and 12 people wounded Friday afternoon through early Saturday; one person killed and 24 people wounded Saturday evening through early Sunday; 13 people wounded Sunday afternoon through early Monday; and 16 people shot Monday into early Tuesday, two of them fatally.

The holiday weekend was police Superintendent Eddie Johnson's first since Mayor Rahm Emanuel picked the veteran cop to lead the embattled department in late March. The department sought volunteers to work overtime over the weekend, although police spokesman Anthony Guglielmi did not release figures on how many officers worked. Instead of hiring more cops during a city budget crunch, Emanuel instead has relied heavily on overtime to try to tamp down violence.

The weekend shooting scenes played out from a gas station in Dunning on the Northwest Side to a narrow tree-lined street in the South Side's West Pullman neighborhood. Residents and passersby at times grabbed towels and ice packs to aid the wounded. Others tried to figure out if the victims were friends or loved ones.

Left mourning were family members, including those of Veronica Lopez. The 15-year-old was the youngest of the homicide victims, shot as she rode with two older men police identified as known gang members along Lake Shore Drive near Fullerton Avenue about 1:30 a.m. Saturday. One of the men also was hit but survived.

That afternoon, her mother, Diana Mercado, wept outside her family's home above a storefront in the Belmont Craigan neighborhood. She said she had begun planning to move with Veronica to Florida in a year because of the city's violence.

"Now they took my baby," she said.

Later that day, in the Lawndale neighborhood, the mother of another teen, Shequita Evans, walked up to a scene of a woman who was shot in the neck while driving down Lexington Avenue near Pulaski Road. Evans lamented that she had to get through "one more summer" until her 17-year-old could graduate high school and attend college outside the city.

At another scene in the Back of the Yards, a woman had to explain to a small boy how the loud pops they had heard weren't fireworks from the White Sox game. The boy smoothed the cape of a Superman doll as he asked officers if they had gotten the bad guys.

In addition to Veronica, the homicides included:

• Mark Lindsey, 25, shot while sitting in a parked car in front of his mother's house in the 3700 block of West 75th Place in the Ashburn neighborhood around 11:20 p.m. Friday.

• Garvin Whitmore, 27, shot in the head about 5:20 p.m. Saturday in the South Side's Fuller Park neighborhood. He was sitting in a car with his fiancee, Ashley Harrison, 26, who picked up a gun and fired warning shots in the air. She was charged with a felony.

• Damien Cionzynski, 25, was shot by one of two men with whom he was arguing inside a BP gas station at Narragansett and Montrose avenues around 5:15 a.m. Saturday. Police have issued arrest warrants for two men.

• James Taylor, 44, was shot in the 5100 block of South Calumet Avenue. Taylor, of the 6500 block of South Ellis Avenue, was pronounced dead at 11:20 p.m. Monday at the scene, according to the Cook County medical examiner's office. He died from multiple gunshot wounds, the office determined following an autopsy Tuesday. Police were called to the scene and found Taylor unresponsive on the street, near a vehicle, said Officer Thomas Sweeney, a police spokesman.

• Johan Jean, 39, was shot in the 6400 block of North Rockwell Street. Jean, of the 100 block of Ashland Avenue in Evanston, was pronounced dead at 11:44 p.m. at St. Francis Hospital, according to the medical examiner's office. He died from a gunshot wound to the neck, the office determined following an autopsy Tuesday. Jean was discovered unresponsive in a gangway, and police said he may have died in a domestic incident.

The tally doesn't count a woman run over on Lake Shore Drive early Sunday. Her boyfriend, who also was hit in traffic, told police they were fleeing a group of armed robbers, and detectives have located evidence of a group of men in the area.

By Tuesday morning, the tally of those shot in Chicago this year was around 1,500, according to data compiled by the Tribune, with at least 250 killed. By this time last year, 957 had been shot, with 164 killed.

So far, shootings are up more than 50 percent this year, although the pace of increased violence had slowed from earlier this year, when Chicago was on track to see shooting victims nearly double.

Chicago police have said the violence has been fueled by gang conflicts and a proliferation of guns, mixed with weak gun law enforcement. The department has blamed most of the violence on a core group of about 1,300 people whom they have used data analytics to pinpoint. The department has called them "strategic subjects."

It can be tougher to pinpoint exactly when that violence can explode, with spikes that can spring up on any warm weekend. Over Mother's Day weekend, more than 50 people were shot, eight fatally, in the most violent weekend in Chicago since September.

The 60 homicides this month have outpaced those in each of the previous three years in Chicago, according to Tribune data. By May 30, 2015, there had been 45 homicides, with 41 by the same date in 2014 and 47 in 2013.

Following are the other shootings from the last 15 hours of the holiday weekend:
